To all whom it may concern:

Be it known that I, WILLIAM. F. BLAKE, a citizen of the United States, residin at Toledo, in the county of Lucas and tate of Ohio, have invented anew and useful Clothes-Washing Machine, of which the following is a specification. j

. My invention relates to improvements in clothes washin machines in which a round tub has a buc et plunger operating inside the tub; and the objects of my invention are, first, to provide a washing machine that cleanses garments quickly and efliciently; second, to construct a machine that will wash thoroughly without twisting or tearing the garments; and third, to provide a washing machine that agitates the water, soap, and clothes thoroughly in conibination without complicated mechanism inside the tub or outside.

I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a vertical section of the, outer tub and inner bucket plunger; Fig. 2, a view of the vertical section of the bucket plunger; and'Fig. 3, a detail View of the base of the bucket plunger.

Similar numerals refer to similar parts throu hout the several views.

Re erring to Fig. 1, the figure 1 indicates the operating lever, 2, the connecting shaft between lever 1 and the cross bar 3 of the bucket plunger 5. 4 shows the side standards and 7 the circular disk which forms the base of the bucket plunger and which is cut out as shown at 16 leaving a wide pressure flange with the bevel 8 to facilitate the upward 10 indicates the upright fastened to the outside of the tub 6 by the rivets 11. 13 and 14 are the pivots connecting the lever 1 with the upright 10 and the shaft 2. 12 is the spring which assists in bringing up the lever 1 and the bucket plunger 5. shows the wall of the bucket plunger 5 and 18 the air space between the base 7 and the bottom of the tub 6. In the operation of my washin machine, water and soap are placed in t e tub 6 filling it to about the same depth as the top of the bucket plunger 5, then the garments are put into the water and inside of the bucket plunger. The bucket plunger 5 is moved up and down in movement of clothes and water;

the tub 6 by means of the lever 1. When the bucket plunger is lifted it carries part of the water and clothes upward with it then avity causes the garments and water to p unge toward the bottom of tub 6 through the opening 16; now when the bucket plunger 5 is pressed down, the circular flange 7 on the bucket plunger displaces the water and clothes causing them to rush rapidly upward through opening 16. This action repeated quickly creates an enormous agitation and intermixing of clothes and water, forcing soapy water constantly through the garments and thus cleansing them quickly without tearing or twistin the fabric.

The ucket plunger or drum 5 provides a receptacle for the clothes and the aperture in the disk 7 of the plunger being considerabl less in area than the area of the tub an the lunger or bucket also quite closely fitting t e tub, movement of the plunger causes the water and clothing to be forced upwardly and downwardly through this central aperture, the rapidity of action being caused b the displacement of the lunger. Whi e gravity ma set on the water particular y on its downward movement upon the upward movement, of the plunger, the principal cause of a 'ta tion however is by reason of the dis acement of the plunger. It is to be note that, on downward movement of the (plunger, water passing therethroulgh is force toward the center with an equa pressure from all sides and upon upward movement of the plunger the water is drawn downward through the lunger moving in the reverse direction wit The clothing in the drum is not caused to become tangled or knotted to any detriequal'pressure on all sides.

have some efmental extent at least because of the fact that the movement of the water and clothing is first for a short period in one direction and then is reversed so that at the finish of a complete upward and downward strokedrum the clothing in the,

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: I

1. In a clothes washing machine, the combination of an outer round tub, a movable, hollow bucket plunger through which the clothing and water may pass, and means for opterating the same vertically in the outer tu 2. In a clothes washing machine, the combination of an outer tub and an inner bucket plunger with an opening in its base through which clothing and Water may pass, fitting loosely in said outer tub and vertically movable therein.

3. In a clothes washing machine, the combination of a tub and a bucket plun er, having a circular wall and a base wit a round central opening therein, approximately two-thirds of the diameter. of 'the bucket plunger. 1 T, tliediameter 0 machine, a verticall movable bucket plunger having a base wit a beveled, centraLE-circuIar opening and a flange adjacent the periphery of said plunger, to agitate and displace water and clothes in combination.

5. In a washing machine, a tub, a plunger or drum movable vertically therein, said drum having a flange providing a central opening less in diameter than the diameter of the drum, the drum loosely fitting in the tub and being open at the top to receive clothing, and means for moving the drum In a washing be passed, means for reciprocating the drum in the tub, the displacement of the drum and flange on downward movement of. the plunger, causing the water and clothing to be forced upward through the central aperture and then downward therethrough on movement of the drum in the opposite direction.

7. An agitating device for liquids comprisin thevc ombination with a tub or receptace, of an open ended flanged drum movable vertically therein, the drum hav- "ing a central opening less in diameter than :the

um, movement of the druma'nd consequent displacement causing a rush of fluid through the central aperture.

8. In a washing machine, a tub for water and clothing arid a vertically reciprocable plunger loosely 'fittting therein and having a central aperture through which the liquid and clothing may pass.
